The MAG-7 is a unique magazine-fed pump-action shotgun. The weapon features favorable battle characteristics as a high damage per shot, good effective range, a high rate of fire, and excellent accuracy. The combination of these traits and tight grouping of the buckshot means that the weapon has an extremely high chance of taking down a target with a single shot, even at medium ranges. The weapon also fires faster when aiming down the sights, a trait shared with the Remington 870 RAS.

The weapon is fed from a 5-round box magazine, making it somewhat less effective for engaging multiple enemies, due to the inability to reload one shell at a time. It is nevertheless extremely well-rounded and suited to almost any combat scenario.
